What Is Chart Vacancy in IRCTC?
By Lokesh Rathore · Last reviewed 26 August 2026
Chart vacancy means the berths that are still empty on a train after Indian Railways has prepared its reservation chart. They are not a glitch and they are not theoretical — they are real seats, and they can be booked.
The term matters because a lot of people assume booking closes once the chart is out. It does not. Whatever is left over is released for current booking and stays purchasable until the train departs.
Where the Empty Berths Come From
A train shown as fully booked weeks earlier routinely leaves with space, for four reasons:
- Cancellations. A large share arrive in the final 48 hours.
- Unclaimed quota berths. Ladies, Senior Citizen, Divyangjan, Duty Pass and Remote Location quotas each hold berths back. Anything unsold at charting returns to the general pool.
- No-shows. Booked, paid for, never boarded.
- Part-route bookings. A passenger travelling only half the route leaves that berth free for the rest.
When Chart Vacancy Appears
At chart preparation — and that timing changed recently. For trains departing between 5 am and 2 pm the first chart is now drawn by about 8 pm the previous night. For trains departing after 2 pm or before 5 am it is about 10 hours before departure. A second chart follows roughly 30 minutes before the train leaves, releasing any further cancellations.
Until December 2025 this was four hours, and before July 2025 it had been four hours for years, so most guidance you will find elsewhere is out of date. Our guide to chart preparation timings covers the change in full.
Chart Vacancy vs Seat Availability
These get used interchangeably and they are not the same thing:
- Seat availability is what is bookable before charting, on any future date within the 60-day reservation window. It is a planning tool.
- Chart vacancy is what is left after charting, on the day of travel. It is a last-minute tool.
If you are booking next month, you want seat availability. If your train leaves tonight, you want chart vacancy.
How to Claim a Vacant Berth
- Current booking online through IRCTC, available from the moment the chart is out until departure.
- The current booking counter at major stations, which sometimes holds stock the online window no longer shows.
- The TTE onboard, for berths left empty by no-shows — allotted to RAC passengers first, then waitlisted passengers on that train.
Reading the Status Codes
- AVAILABLE-0042 — 42 berths free.
- CURR_AVBL — current availability, released after charting. This is chart vacancy in its literal form.
- RAC 12 — a shared side berth rather than a full one.
- GNWL24/WL11 — waiting list, booked at 24 and now at 11.
- REGRET — no further booking in that class.
Where the Official Chart Lives
Indian Railways publishes the real berth-by-berth chart itself, free and without a login, at IRCTC Online Charts. That is the authority on which specific berth in which coach is empty. Tools like this site are for speed — comparing dates and classes quickly — not for replacing the official chart.
A Realistic Expectation
Chart vacancy is genuinely useful on ordinary days on busy routes, where cancellations are constant. It is close to useless during Diwali, Chhath, Holi and the summer holidays, when almost nobody cancels. Knowing which of those you are in saves a wasted trip to the station.
Frequently Asked Questions
Chart vacancy is the set of berths still empty after Indian Railways prepares a train's reservation chart. They arise from cancellations, unclaimed quota berths, no-shows and part-route bookings, and they can be booked through current booking until the train departs.
No. Seat availability is what is bookable before charting, for any future date inside the 60-day reservation window — a planning tool. Chart vacancy is what remains after charting, on the day of travel — a last-minute tool.
Yes. Berths left free after charting are released for current booking, both online through IRCTC and at the station's current booking counter, and stay bookable until the train leaves. Berths freed by passengers who never boarded can also be allotted onboard by the TTE.
When the first chart is prepared: by about 8 pm the previous night for trains departing between 5 am and 2 pm, or about 10 hours before departure for trains departing after 2 pm or before 5 am. A second chart around 30 minutes before departure releases further cancellations.
Indian Railways publishes it free and without a login at irctc.co.in/online-charts. It shows coach numbers, berth numbers and which berths are vacant, and it is the authoritative source.
Much less so. Chart vacancy depends on people cancelling, and around Diwali, Chhath, Holi and the summer holidays cancellations fall close to zero. On ordinary dates on busy routes it works well; on peak dates you should not plan around it.
